  • In this paper we study the multifractal structure of Schramm’s SLE curves. We derive the values of the (average) spectrum of harmonic measure and prove Duplantier’s prediction for the multifractal spectrum of SLE curves. The spectrum can also be used to derive estimates of the dimension, Hölder exponent and other geometrical quantities. The SLE curves provide perhaps the only example of sets where the spectrum is non-trivial yet exactly computable.

  • Food availability, access, stability and utilization are all part of the multi-dimensional nature of food security. The “availability” aspect, discussed here, refers to the availability of sufficient quantities of food of appropriate quality, supplied through domestic production or inputs. Productivity is usually considered the ultimate benchmark when comparing the performance of agricultural systems. For example, those involved in agricultural research and development want to know how much yield would be reduced if conventional agriculture were converted to organic agriculture.

  • Sensitivity Analysis Sensitivity analysis allows you to analyze how various measured quantities (parameters) vary when a model dimension or an independent model parameter is varied within a specified range. The result is a graph for each selected parameter showing the value of the parameter as a function of the dimension. This provides for understanding exactly how geometric changes to your model will affect your engineering goals or specifications.

  • Standards Measurement is the process by which a quantitative comparison is made between a standard and a measurand. The measurand is the particular quantity of interest—the thing that is to be quantified. The standard of comparison is of the same character as the measurand and, so far as mechanical engineering is concerned, the standards are defined by law and

  • Tools shape how we think; when the only tool you have is an axe, everything resembles a tree or a log. The rapid advances in instrumentation in the last decade, which allow us to measure and manipulate individual molecules and structures on the nanoscale, have caused a paradigm shift in the way we view molecular behavior and surfaces. The microscopic details underlying interfacial phenomena have customarily been inferred from in situ measurements of macroscopic quantities. Now we can see and “finger” physical and chemical processes at interfaces.

  • For the reflection or describing, with accuracy, an appearance (substance, quantity); material or psychological status of the research subject, are needed to measure them as definite standards. The measurement is not only the definite size of physical dimension but also whatever concepts, which can be compared each other.

  • Computing the usual productivity measures requires data on the value of transactions and either prices or quantities. In the final research study of this volume, Erwin Diewert notes that Canada lacks direct price and quantity measures for many important services industries. Other nations also have this problem. As a result, the usual productivity indexes cannot be evaluated properly for those services industries, nor can we get a complete picture of productivity performance for the economy as a whole.

  • Excluded from the defi nition of “swap dealer” are entities entering into swaps for their own account and “not as part of a regular business.”16 Accordingly, it is likely that many private funds would be excluded from the defi nition, in the same way that private funds are generally considered to be “traders” and not “dealers” under Section 3(a)(5) of the Exchange Act because they buy and sell securities for their own account and not as part of a regular business. Additionally, a person or entity that engages in a de minimis quantity of swap dealing is not...

  • The Semantic Web [22] holds out a different vision, that of information laid bare so that it can be collected, manipulated, and annotated independent of its location or presentation format- ting. While the Semantic Web promises much more effective access to information, it has faced a chicken-and-egg problem getting off the ground. Without substantial quantities of data avail- able in Semantic Web form, users cannot benefit from tools that work directly with information rather than pages, and Semantic Web-based software agents have little data to show their useful- ness.

  • A decrease in demand – such as occurred for typewriters with the advent of computers, or buggy whips as cars replaced horses as the major method of transportation – has the reverse effect of an increase, and implies a fall in both the price and the quantity traded. Examples of decreases in demand include products replaced by other products – VHS tapes were replaced by DVDs, vinyl records replaced by CDs, cassette tapes replaced by CDs, floppy disks (oddly named because the 1.

  • One reason why the study of thermodynamics is so valuable to students of chemistry and chemical engineering is that it is a theory which can be developed in its entirety, without gaps in the argument, on the basis of only a moderate knowledge of mathematics. It is therefore a self-contained logical structure, and much benefit--and incidentally much pleasure-may be obtained from its study. Another reason is that it is one of the few branches of physics or chemistry which is largely independent of any assumptions concerning the nature of the fundamental particles.

  • To research the volume and components of solid waste, we surveyed household waste with three different incomes (high, middle and low incomes). Then waste is separated into 34 waste components and 9 main waste groups containing organic waste (easily decomposed waste such as vegetable, root, fruit, left food.. to make the compost and difficultly decomposed waste), paper, plastic, metal, glass, rubber and leather, cloth, dangerous substance, and other waste. Besides, definition of all groups of waste is also discussed. ...

  • Through the use of abstraction and logical reasoning, mathematics developed from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity for as far back as written records exist. Rigorous arguments first appeared in Greek mathematics, most notably in Euclid's Elements.

  • Calibration is the most important step in bioactive compound analysis. A good Precision and accuracy can only be obtained when a good calibration procedure is adopted. In the Spectrophotometric methods, the concentration of a sample cannot be measured directly, but is determined using physical measuring quantity ‘y’ (absorbance of a solution). An unambiguous empirical or theoretical relationship can be shown between this quanity and the concentration of an analyte.

  • Cambridge researchers César Milstein and George Köhler won a Nobel Prize in 1984 for their work developing monoclonal antibodies (mAbs). Each mAb is a specific antibody, a ‘magic bullet’ protein that targets and attacks one particular substance or cell. Milstein and Köhler found a way to produce these magic bullets in unlimited quantities. mAbs are proteins produced in the laboratory from the cells of the immune system that make antibodies.

  • CHAPTER FOCUS Estimation Problem This is the problem of estimating the state of a linear stochastic system by using measurements that are linear functions of the state. We suppose that stochastic systems can be represented by the types of plant and measurement models (for continuous and discrete time) shown as Equations 4.1±4.5 in Table 4.1, with dimensions of the vector and matrix quantities as shown in Table 4.2.

  • Electric charge and a measure for the quantity of charge Any household electrical appliance – be it a light bulb, a motor, or a television set – has two contacts which have to be plugged in to get the device to operate. This common characteristic, that an electrical apparatus must have two wires connecting it to a source of electricity, gave the rise in the eighteenth century to the idea that when an electrical device is working, something is moving through it. That something is called electric charge. When you pull out a plug, turn off a switch, or disconnect...
